Removal

1 Remove the steering wheel.
2 Remove the airbag clock spring and Fiat Punto steering column stalk switches.
3 Where fitted, undo the retaining bolts and remove the metal guard plate beneath the power steering electric motor.
4 Disconnect the two main wiring harness connectors from the power steering electric motor ECU (see illustration).

5 Disconnect the wiring connector from the rear of the Fiat Punto ignition switch/column lock (see illustration).

6 Working in the driver's footwell, unscrew the clamp bolt retaining nut on the intermediate shaft lower universal joint (see illustration). Remove the clamp bolt from the retaining clip on the universal joint. Make suitable alignment marks on the steering gear pinion and universal joint to ensure correct orientation when refitting.

8 Disconnect the universal joint from the Fiat Punto steering gear pinion, and remove the steering column from the car.

Overhaul

9 The height adjustment mechanism can be removed by removing the nut from the end of the pivot shaft and withdrawing it.
10 The upper and lower bushes are held in position by staking at the ends of the column tube. Relieve the staking using a mallet and punch to extract the bushes.
11 Check for excessive radial and axial play in the universal joints at both ends of the steering column intermediate shaft. The intermediate shaft may be renewed separately, if required, by slackening the clamp bolt and detaching it from the column upper section.
12 If the vehicle has been involved in an accident, check for deformation in all of the steering column components, particularly the mounting bracket and centre tube. Renew as required.

Refitting

13 Refitting is a reversal of removal, bearing in mind the following points.
a) Ensure that the roadwheels are in the straight-ahead position then engage the universal joint with the steering gear pinion aligning the marks made on removal.
b) Tighten ail retaining nuts and bolts to the specified torque.
c) Refit the steering column stalk switches and airbag clock spring.
d) Refit the steering wheel of Fiat Punto.
